Paul McCartney on Becoming the Bass Player in the Beatles

"Stuart [Sutcliffe] decided to leave the band, and there was this sort of ceremonial handover of the bass to me. But he was only lending it to me, so he didn't want me to change the strings around. Of course, he was right-handed and I'm left, so I had to learn how to play upside down, if you will. Eventually, I got my own bass and it was set for a left-hander. Then it felt a lot more natural. But I was a guitar player before that and I kind of inherited the bass position. I was always a kind of frustrated guitarist who played bass."
